25 Claims.

My invention relates to typewriting, combined typewriting and computingand like machines and more particularly to a typewriting or like machinein which there is av plurality of sets of printing instrumentalitiesoperated by a single set of printing keys.

One of the primary objects of my invention, generally stated, istoprovide highly eicient mechanism of the character specified that isdurable, reliable in its operation and comparatively simple in itsconstruction.

Another object of^my invention is to Iprovide compartively simple andimproved means whereby identical entries may be simultaneously printedin a plurality of `columns on a Work sheet or sheets by the actuation ofa single set of printing keys. y

A further object of my invention is to provide in a typewriting or likemachine of the character specified having a carriage fitted forstepby-step letter spacing movement, a plurality of sets oi' printinginstrumentallties which are power-actuated under the control of a singleset of printing keys.

Another object of my invention is to provide a plurality of type barsegments and actuating means for the type bars thereof, which may bemounted within the limits of a typewriter frame of the usualconstruction without materiali modifying said frame.

Another object of my invention is to provide means of the abovecharacter which may be applied in the nature of an attachment to astandard machine without materially modifying said machine. v

A further object of my invention is to provide in a machine having aplurality of sets of printing instrumentalities means for automaticallyrendering said instrumentalities of certain sets ineffective orinoperative while those of the other set or sets remain effective.

Another object of my invention is to provide a machine of the characterlast referred to in which the means for rendering the printinginstrumentalities effective or ineffective is controlledby the travel ofthe carriage.

Still another object of my invention is to provide a. typewritingmachine having a plurality of type bar segments, @separate printingcenter for the type bars of each segment, and means for silencing theactuation of the type bars of one or more of said segments.

The present invention has for a further object to so construct thecontrol devices for the print- KK ing instrumentalities that they willbe compact in structure and highly effective in use and may be readilyincorporated in existing machines Without modifying or materiallymodifying, the existing structural features of such machine.

To the above and other ends which will here- 5 inafter appear myinvention consists in the features of construction, arrangements ofparts and combinations of devices set forth in the follow`ingdescription and particularly pointed out in` the appended claims l0In the accompanying drawings wherein like reference characters designatecorresponding parts in the different views:

In the present instance I have shown three forms of my invention. Thefeatures of two of these forms have been embodied in a No. 85 Remingtonelectrified bookkeeping machine and within the limits of the framethereof. Baid machine is equipped with computing mechanism similar tothat disclosed in the patent to Wahl No. 1,270,471 dated June 25, A1918,the machine being power actuated in a manner as set forth in theapplication of F. A. Hart Serial No. 510,941 filed January 24, 1931. Thethird form has been applied to a machine of the above mentioned typeinthenatureofanattachment. Whilethedevices of my present invention maybe incor i combined typewriting and computing machine,

but that it may be employed in like machines generally, wherever foundavailable.

In the accompanying drawings I have shown only so much of the frame,computing mechanism and power drive of the No. 85 Remington electriedbookkeeping machine as is necessary to arrive at an understanding of thefeatures of my present invention in their combination therewith.Reference may be made to the above mentioned patenth and application fora description of any of the computing mechanism which these drawings donot show and which Remington bookkeeping machines include, or anymechanism which is particularly referred to and not fully illustratedherein.

In various forms of billing and oilice recording oftentimes it isdesirable to type the same item in a plurality of columns either atdefinite spaced intervals on one sheet or in separate columns on aplurality-of sheets. When such columns of amounts are printed on onework sheet, said sheet is usually in a form which may be readilydetached into a plurality oi' sections which in turn are used fordifferent purposes. However,- the identical items which appear indiiierent columns may be printed on a plurality of sheets if desired,though the advantage and ease of handling a single sheet will be readilyappreciated.

In order that the operator will not have to Ixtnake a separate entry ofthe data in each coltaneously operating the printing instrumentalitiesof each set, all of said mechanism being mounted in a suitable framestructure which is provided with a carriage fitted for step-by-stepletter spacing movement.

In the present instance, I have shown several forms of constructionembodying my invention. These various forms of construction include onein which two sets of printing instrumentalities are mounted within theusual typewriter frame; another in which four sets of printinginstrumentalities are mounted within the usual typewriter frame; andanother in which there are two sets of printing instrumentalities, butone is provided in the nature of an attachment at the side of anordinary typewriting machine, for exampie a Remington electrifiedbookkeeping machine, which has been slightly modined as will hereinafterappear.

DUAL Smumr MACHINE I shall first describe the form of constructionembodying my invention in which there are two sets of printinginstrumentalities mounted in the usual frame structure of an ordinarypower actuated bookkeeping machine.

' Pbr making out certain classes of bills the use of numeral printingtypes and certain special types of a character to be described alone arerrequired, other data which requires the use oi the alphabet types beingtaken care of by the printed forms or other means. So therefore, in thepresent embodiment of my invention about to be described, I employ onlynumeral printing instrumentalities and certain Vspecial mark printinginstrumertalities, although of course this may be varied at will.

In the machine as shown in Figs. 1 and 2, the mechanism is preferablyincluded in two units in one of which the parts are carried by a framedesignated as a whole by the reference numeral 20, that is much the sameas the frame of the No. 85 Remington electried bookkeeping machine,whereas the parts of the other unit are carried by a second frame 2|that constitutes a base on whichvthe frame 2|) rests and to which it ispivotally united by any suitable means. The coacting working partscarried by the frames 20 and 2| are so related that the upper frame 20may be swung on the base 2| and maintained in an upward open position,in order to give access to the parts contained within the frame 20 a`tthe lower portion thereof, and also to give access to the underlyingparts rcontained within the base frame 2|. When the"frame 20 is loweredon the base frame 2| and secured thereto, the coacting parts on the twoframes will be brought into cooperative relation ready to function in amanner that will hereinafter be more fully described.

The upper frame 20, comprising corner posts 22 and top plate 23,supports a carriage 24 which is of the usual construction and carries aplaten 25. The carriage 24 is mounted in the usual manner on rollerbearings 26 to travel over the top plate 23 ofthe machine from side toside thereof, the bearing rollers being supported in the grooved Ways inxed guide rails 21 secured to the top plate of the machine. Saidcarriage is spring impelled in the direction of its feed by the usualspring drum (not shown) Aunder control of the usual escapement mechanism(Fig. 2) which is designated as a whole by the reference numeral 28 andcomprises the usual feed rack 29, pinion 30, escapement wheel 3| and dogrocker 32 having a depending arm 33. A step-by-step let'zei spaceadvance of the carriage is eiected in the usual manner during theoperation of the type bars as will presently appear.

Referring particularly to Figs. 2 and 6, it will be seen that a specialcasting 34, which will hereinafter be referred to as the dual segment,replaces the ordinaryv type bar segment and is mounted in the machine bymeans of screws 35 engaging in tapped openings 3B provided in the usuallugs 31 on the top plate 23. The lugsl 31 are the same as those providedin the usual machine frame for the mounting of the regular type barsegment. prises aleft-hand segment orsegmental portion A and aright-hand segment or segmental portion B.y Each of these segments A andB is radially slotted at 38 to receive and guide a set of printinginstrumentalities or type bars 40, thetype bars of each segment beingpivoted on a` separate fulcrum or pivot wire 4|. When the type bars 40are at rest they occupy a substantially horizontal position upon a rest42 (Fig. 1) and the construction is such thatV the type bars in segmentA may be moved in radial planes upward and rearwarf from their normalresting position and through one of the usual typeguides 43 to strike ata common printing. center P* on the.

front portion of the platen 25.. Likewise the type This dual segmentcasting 34 com-- bars of segment may 'be -s'w'ng upward and rearwardthrough a second type guide 44 to strike the platenA at a commonprinting center Pb which is separate and distinct from the printingcenter for the type bars of segment A. As shown in Fig. 6 the printingpoints are at equal distances on either side ofthe center line of themachine.

In the present instance the segmental portions A and B each correspondsto some portion of one of the usual type bar segments for a fullcomplement of printing instrumentalities. 'Ihat is, each radial slot 38occupies a position corresponding to that of some particular slot of aregular ksegment so that regular type bars, bell cranks, sub-levers, keylevers etc. may be used to carry out my invention. 'Ihe segmentalportions are similar to a regular segment further in that each isprovided with an arcuate anvil 45 on the forward Aside of the castingand an arcuate groove 46 on the rearward side for the receptiton. of acurved universal bar 41. The arcuate grooves 46 are near the lower edgesof the segments A and B and cross the slots 38 so that the usual curvedheel portion 48 of each type bar will project through its slot 38 andinto the groove 46 when the type bar is swung up to the platen.

For the reasons which will hereinafter appear, it is desirable in thepresent instance, to provide a universal bar 41 in the groove 46 ofsegment A only. This universal bar is` contacted in a well known mannerby the heels 48 of the type bars of segment A as they swing to printingposition, and such contact causes said bar to move rearwardly. A pin 50is attached to an ear 5I provided on the universal bar 41 at a centralportion thereof, and said` pin registers with a circular opening 52 inthe segment casting to guide said bar 41 in its rearward movement. Themovement of the universal bar 41 is transmitted by a pair of arms 53 toa pivoted frame, designated as a whole by the reference numeral 54. Thisframe is the same as those used in regular machines and is pivotallysupported at its ends by means of pointed screws 55 on a pair ofbrackets 56, which extend downward from the top plate 23. The frame 54is used to transmit the motion of the universal bar to the dog rocker 32and comprises three upwardly extending slotted arms 51, 58 and 59, thefirst two of which have the arms 53 of the universal bar pivotallyconnected thereto as by means of a screw or pin 60. A link 6| completesthe train of connections to the depending arm 33 of the dog rocker 32,said link being bifurcated at its forward end and straddling the pin 60of the arm 58 and also bifurcated at its rearward end and engaging aheaded pin 62 on the depending arm 33 of the dog rocker.

Thus it will be seen that when one of the type bars in segment A isvswung to printing position it will effect a rearward movement of thelink 6| through the movement of the universal bar 41. 'I'his motion istransmitted to the dog rocker 32 to effect a letter space movement ofthe carriage. When the type bar is returned to its resting position theuniversal bar will likewise be moved back into the groove 46 by means ofthe usual returning spring mechanism (not shown) employed in conjunctionwith the pivoted frame 54.

In the present instance, the left-hand segmental portion Agis providedwith a set of thirteen of the printing instrumentalities or type bars40.

' This set includes ten numeral type bars for the
